Magnetic and vibronic THz excitations in Zn doped Fe${}_2$Mo${}_3$O${}_8$

B. Csizi, S. Reschke, A. Strinic +4

We report on optical excitations in the magnetically ordered phases of multiferroic Fe${}_{1.86}$Zn${}_{0.14}$Mo${}_3$O${}_8$ in the frequency range from 10-130 cm${}^{-1}$ (0.3-3.9 THz). In…
